A phenolic modified alkyd is an alkyd that has been altered with phenol. It is a polyester coating that has fatty acids in its composition. Phenolic modified alkyds are commonly used as primers or paints for corrosion prevention purposes rather than for aesthetic reasons. Advertisement Corrosionpedia Explains Phenolic Modified Alkyd A phenolic modified alkyd uses phenols to increase the alkyd’s original properties. The use of phenols decrease the detrimental effects that grease, oil, abrasion and water can have on an alkyd coating. If used as a primer, phenolic modified alkyd coatings can have subsequent layers of other types of coatings added on top. Phenolic modified alkyds are categorized by the length of oil in their resin. These categories are short, medium and long. The viscosity of the alkyd will be higher the shorter the oil length of the resin is. If it is a short oil length, it will also have less flexibility. When using phenolic modified alkyd coatings, it is important to make sure the base material is clean prior to application. Phenolic modified alkyd coatings can be applied by rolling, brushing and spraying.
